mp3 in objects...
Mp3 files in an object ask for a media player to be installed. In IE media player plays the file OK.
In Firefox when no player is installed quick time is proposed.
when installing VLC player in stead of quick time, the plugin is waiting for video and no sound is played. (bug VLC player or chamilo??)
So in firefox it is not possible to play mp3 without apple quicktime.=> (in Linux no mp3 playback in document possible.)
to complicated.... Flash player from in Chamilo 1.8.6.x
